Nenad Krstic is thankful the NBA in general and the Nets in particular don’t sponsor “Rotgut Liquor and Automobile Flares Night.”

Yes, Krstic saw film of the outrageous riot by fans in the stands of the Red Star Belgrade-PAOK game in his native Serbia. Though it seems nearly impossible, it made the rumble at the Palace of Auburn Hills seem tame. For starters, folks in Serbia were brandishing flares.

“That’s a usual thing in Serbian games,” Krstic said with a shrug. “Last season, it was the same. Maybe worse when it was Red Star against my ex-team. But fights in games, soccer games, basketball games, they’re usual. It happens a lot . . . When they start throwing the flares, it’s very dangerous.”

Krstic acknowledged he has been pelted with rocks, eggs, coins and the all-purpose cigarette lighter in the past.

“They throw everything. Coins, all the time,” said Krstic, who stressed the Serbian government is beginning to crack down on the violence and search people as they enter the games, apparently looking for rocks, cigarette lighters, eggs – and flares. “They’re going to start doing it like this country. Before you come to game they check you.”

So the occasional booing from Nets’ fans doesn’t seem so bad.

“It’s nice,” Krstic said of the Meadowlands. “Without fights, it’s very nice to play. They cheer and see you play the whole game. You can get used to that.”

Eddie House shot 1-for12 in his first two games back from surgery on his left knee. Although he fed into the team line that everyone must improve, he immediately added himself.

“Our effort can be better. And that means everybody. I know I can play a little harder,” House said. “It would be bad for me to not talk about myself. The Dallas game was one of the most disgusting games I ever played: 11 minutes, not a rebound, not a steal, nothing. It’s a good thing that it was one day. So get it right, come right back and play again.”

Coach Lawrence Frank on mentor Bobby Knight tying Adolph Rupp while chasing Dean Smith for most career NCAA coaching wins: “It’s an unbelievable accomplishment and achievement. For someone who’s been such a strong influence in my life, you’re just glad to see one tangible thing that shows what a great coach he is.”
